user.avatar will always return nil

[Mycroft Canner]

    public var avatar: URL? {
        return rawResponse.hdProfilePicVersions
            .array?
            .first?
            .url
    }

.first? is a dictionary

[Stefano Bertagno]

I see what you mean.
There's definitely a .url missing there. @mycroftcanner
Fixing it in #96.
Apologies
